To all wwnt t muy concern:

Be it known that I, EDWARD G. J oHNsoN,a.

citizen of theUnited States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in-jV vented certain new and useful Improvements in Pads or Supports for Ice, of which the fol-. lowing is a specication.

My invention has relation to a pad or supxo port upon which ice may be placed and whichy not only forms a yielding or elastic support for the ice, but also serves as an insulation to prevent too-rapid melting of the ice resting upon the pad or support, as Well 'as a recepi 5 tacle or container for drippings of the ice, and

by circulation of air in the chamberv or box inV which the pad or support is mounted permitting of the evaporation of the drip-Water iiovv`V ing into the pad or support, thereby always in zo use maintaining the ice supported by the pad in a comparatively dry state underalowered temperature,assisted by the circulation of the air for the maintenance of such conditionY ofY the chamber and ice therein g and in such conl r 5 K nection it relates more particularly to the conport is mounted permitting of the evaporation'- of the drip-water carried into the pad orsupport.v

The nature and object of my invention will be more fullyunderstood from theA following description, taken in connection with the accompanying drawings, forming part hereof, in Whichi Figure l is a perspective vie W of a refrigerator With the ice-chamber partly broken away to illustrate the pad embodying main features of my invention in operativeposition in said chamber. Fig. 2 is a topor plan View, en-

chamber f,' as Villustrated in Fig. 1. block d of ice is then placed 'upon the pad A. 8o

larged, of the pad embodying my invention. 5o Fig. 3 is a cross-sectional view, still further enlarged, of the pad; and Eig; 4 is a vieu7 similar to Fig. 3, but taken at right angles to the viewin Fig. 3. .Y

VReferring-to the drawings, the pad A consists, essentially', of a sheet opV ,of hair-felt or similar porous, spon gy, o r pilous material so bound or held together by a-perforated metallicor similar casing b as to prevent its disintegration under the influence of either mois- 6: ture or pressure.

- As illustrated in Figs. 2,3, and 4, the sheet d of hair feltis inclosed or sheathed by a Wire-netting l?, so that both ofthe faces of the sheet a are protected Ybya perforated metallic sheet l?, and the edges of the sheet a are likewise protected either by the netting l) *or by tying-wires h', as clearly' illustrated.

`to prevent'the compressionoil the sheet a beyoud its point of resiliency under the Weight of the cake of ice d, supported upon the pad.

In use the pad A is placed either upon the metallic door of the ice-chamber f or upon a shelf or lattice-works on the base of said The ber bottom, which cushionis" not. only elastic or resilient, but also porous. -iIt'also acts as a receptacle or container to absorb the drip- Water from the melting of the` ice, and the 9o continuous circ nlation. of air Within the chamber or box in which the pad supporting the block of ice is contained also serves to evaporate the drip-water -passing or iiowing onto the pad, and thus to lower the temperature of the chamber or box, and hence retard the Moreover, by the absorption of the water from the ice by the pad and the evaporation of the same on the pad by the circnlating'air of the chamber or box the ice supported Within the same upon said pad is maintained at all times in a comparatively dry state, and thus is effected a great saving in the melting of the ice. The ice normally resting upon the metallic netting b of the pad as the sheathing therefor embeds itself into the ice, and thus while supporting the same as a pad maintaining the ice as a xture to avoid displacement of the ice in the chamber or other receptacle.

Having thus described the nature and object of my inventiomwhat I claim as new, and desire to secure by Letters Patent, is-

A pad or support for ice, consisting of hair felt sheathed by a netting to protect the felt
